When the first drivengear 40 and the second drivengear 50 rotate, the firstlight transmitting portion 62 and the firstlight receiving portion 63 of thefirst photo interrupter 60 optically scan the plural fourthtransparent zones 511, the plural fifthtransparent zones 512, and the plural sixthtransparent zones 513 which form the plurality of transparent zones of varying diameter and width successively arranged around the end surface of the first drivengear 40 so that the first transistor 65 of the first photo interrupter 60 accurately judges a rotating position of the second drivengear 50, and thefirst photo interrupter 60 transmits a signal to the central controllingunit 80 via thefirst transmission line 66, hence the central controllingunit 80 controls the drivingmotor 20 to drive the second drivengear 50, and the second drivengear 50 axially rotates to compensate a unreached distance of the second drivengear 50 to a second destination position, then thelocking head 91 reversely rotates. On the contrary, when thelocking head 91 is locked in the remote control mode, and the central controllingunit 80 controls the drivingmotor 20 to drive thedriving gear 30, then thedriving gear 30 meshes with and drives the first drivengear 40 and the second drivengear 50 to rotate reversely, such that the first drivengear 40 and the second drivengear 50 drive the stem K2 to rotate in the multi-section controlling manner, thus locking the locking head 91 (i.e., in an extending state). When the first drivengear 40 and the second drivengear 50 rotate, the second light transmitting portion 72 and the second light receiving portion 73 of the second photo interrupter 70 optically scan the plural firsttransparent zones 411, the plural secondtransparent zones 412, and the plural thirdtransparent zones 413 which form the plurality of transparent zones of varying diameter and width successively arranged around the end surface of the first drivengear 40 so that thesecond transistor 75 of the second photo interrupter 70 accurately judges a rotating position of the first drivengear 40, and thesecond photo interrupter 70 transmits a signal to the central controllingunit 80 via thesecond transmission line 76, hence the central controllingunit 80 controls the drivingmotor 20 to drive the second drivengear 50, and the first drivengear 40 axially rotates to compensate an unreached distance of the first drivengear 40 to a first destination position, then thelocking head 91 rotates forward. - Thereby, the first light transmitting portion and the first light receiving portion of the first photo interrupter optically scan the plural fourth transparent zones, the plural fifth transparent zones and the plural sixth transparent zones which form the plurality of transparent zones of varying diameter and width successively arranged around the end surface of the first driven gear so that the first transistor of the first photo interrupter accurately judges the rotating position of the second driven gear, and the second light transmitting portion and the second light receiving portion of the second photo interrupter optically scan the plural first transparent zones, the plural second transparent zones, and the plural third transparent zones which form the plurality of transparent zones of varying diameter and width successively around the end surface of the first driven gear so that the second transistor of the second photo interrupter accurately judges the rotating position of the first driven gear. Thereby, the central controlling unit controls the first driven gear and the second driven gear to axially rotate so as to compensate unreached distances of the first driven gear and the second driven gear to the first destination position and the second destination position, hence the locking head rotates forward and reversely.
- While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
